Description

Allows to draw rounded rectangles. Parameters are:

x, y: top left corner of the rectangle.
w, h: width and height.
r: radius of the rounded corners.
style: same as Rect(): F, D (default value), FD or DF.

Remark: there's another version of this script that allows to choose what corners should be rounded.

Example

<?php require('rounded_rect.php'); $pdf=new PDF(); $pdf->AddPage(); $pdf->SetLineWidth(0.5); $pdf->SetFillColor(192); $pdf->RoundedRect(70, 30, 68, 46, 3.5, 'DF'); $pdf->Output(); ?>
